Propanediol (1,3-Propanediol) is a bio-based humectant and co-solvent produced from fermented corn sugar. As a 100% plant-derived ingredient, it is widely chosen by natural and clean-label cosmetic brands as an alternative to petroleum-derived solvents. In cosmetic formulations, propanediol contributes to a moisturised feeling on the skin surface. Its lower viscosity and lighter texture make it especially well-suited to serums, essences, toners and lightweight moisturisers where a non-greasy finish is desired. Propanediol also functions as an effective co-solvent for fragrance oils, essential oils and botanical extracts that may be difficult to incorporate in water-based formulas. It helps disperse actives such as niacinamide and vitamin C derivatives evenly throughout a formulation and contributes to overall product stability. Formulators working on natural, organic or clean-label products value propanediol for its biodegradability, non-irritating profile and plant-based origin. Recommended use level: 2–20%. Add to water or oil phase. Suitable for face serums, moisturisers, hair conditioners, toners, eye creams and body lotions. For external use only. Not for internal use.

Why Formulators Choose Propanediol

Propanediol (1,3-Propanediol) is a 100% plant-derived humectant and co-solvent produced from fermented corn sugar. It is widely used in natural, organic, vegan, and clean-label cosmetic formulations as a sustainable alternative to petroleum-derived glycols.

In skincare formulations, propanediol helps attract and retain moisture, leaving the skin feeling soft, smooth, and hydrated without a sticky after-feel. Its lightweight texture makes it ideal for face serums, hydrating toners, essences, eye creams, and lightweight moisturisers.

Propanediol also improves the solubility and dispersion of difficult-to-dissolve ingredients such as essential oils, fragrance oils, botanical extracts, niacinamide, and vitamin C derivatives, contributing to better formulation stability and performance.
